Firefighters and police were called Aug. 19 to the Sigma Alpha Epsilon house in the 300 block of Tallawanda Road.

Officers said they saw SAE and Phi Kappa Tau members shooting fireworks at one another from third-floor windows of their adjacent houses.

Police said the students would not cooperate with their investigation, so officers returned with search warrants.

Officers said they seized drugs and other evidence from the Sigma Alpha Epsilon fraternity.

Six SAE members and one PKT member were charged Friday on various drug offenses.

SAE members William Acker, 21, Noah Kleiman, Benjamin Cohen, 20, and Charles Hodge, 21, were each charged with possession of marijuana. Another member, 20-year-old Nicholas Jurden, was also charged with possession of cocaine and marijuana and drug trafficking. Members Hodge and 21-year-old Patrick Baudhuin were charged with possession of fireworks. Some of them were also charged with possession of drug paraphernalia.

PKT member Willison Evans, 19, was charged with possession of hashish.

The Phi Kappa Tau chapter sued the university for $10 million, saying officials acted with "malice, hatred and ill will" by suspending the organization after the fireworks battle.

The suit claims university officials violated members' constitutional rights by suspending the fraternity without providing an appeal process and despite the fact that police had not filed charges.
